The OPC UA for PROFINET Remote IO Information Model aims to offer Clients Objects and Services based on two RIO application profiles: Remote IO for Factory Automation (see [RIO FA]) and Remote IO for Process Automation (see [RIO PA]).

OPC UA for PROFINET Remote IO consists of all Objects and types provided by an OPC UA Server allowing OPC UA Clients to access the IO data of PN Submodules. The Information Model is divided into a PROFINET aspect offering detailed Telegram information and a functional aspect modelling Process Values as part of RIO Channel Objects. The two aspects offer different access paths for Clients and are connected by dedicated References to allow navigating to the preferred representation from either aspect.
